General Description
1.1 Introduction
The MC68HC908GZ60, MC68HC908GZ48, and MC68HC908GZ32 are members of the low-cost,
high-performance M68HC08 Family of 8-bit microcontroller units (MCUs). All MCUs in the family use the
enhanced M68HC08 central processor unit (CPU08) and are available with a variety of modules, memory
sizes and types, and package types.
The information contained in this document pertains to all three devices with the exceptions noted in
Appendix A MC68HC908GZ48
1.2 Features
For convenience, features have been organized to reflect:
